ABSTRACT:
A method for electronically controlling a fuel injection device which injects fuel into an internal combustion engine, so as to supply a required quantity of fuel to the engine when it is accelerating. It is determined whether or not the engine is operating in a predetermined accelerating condition or in a predetermined decelerating condition, in synchronism with generation of pulses of a control signal having a constant pulse repetition period and being independent of rotation of the engine. When the engine is determined to be in the predetermined accelerating condition, fuel injections are consecutively effected a predetermined number of times in synchronism with generation of pulses of the above control pulse. The above consecutive fuel injections are continued until the above predetermined number of times are reached, so long as the engine is determined not to be in the above predetermined decelerating condition. Preferably, the value of the above predetermined number of times of consecutive fuel injections is set in dependence on the temperature of the engine, and the quantity of fuel to be injected per each of the above predetermined number of times is set in dependence on the rate of change of the throttle valve opening.
